I can see the possibility of that in theory. However, I don't see that it particularly applies any more to a Guard than to anyone put in charge of a party who is incompetent. Only that if one is present, command of a party tends to be given to the ranking Guard...
Can you give any actual examples of where this has happened on a game that would not have been the case if a different party member had had command?
